RAzoR-sTROP-PING Isl-:viesv SPECIFICATION forming part` of Letters Patent No. 7 25,4149, dated April 14, 1903. Application filed August 1,'1902. Serial No. 118,023. (No inodcLl T all whom, it mfr/,y concern.' .l Be it known that we, FREDERIOKKAMPFE, RICHARD KAMPFE, and OTTO KAMPFE, citizens of the United States, Aresiding in New York, borough of Brooklyn, and State of New York, have invented certain new and useful Improvements in Razor-Stropping Devices, of

which the following is a specification.

The razor-stropping device forlwhioh Letters Patent No. 405,961 were granted to us on June 25, 1889, comprised tWo parallel spindles, of which one carried a blade-holder and the other a friction-roller, and gearing for transmitting motion from the spindle carrying the blade-holder to the spindle carrying the friction-roller.

gject of the present invention, therefore, is to vention consists of a razor-stropping device so improve the razor-stropping device hereinbefore referred to that the blade-holder and friction-roller are arranged at an obtuse angle of inclination to the-axis of the handle of the blade-holder, so as Vto apply the new principle discovered by us to the-razor-stropping device heretofore patented by us, and produce thereby a greatly-improved razor-stropping mechanism; and for this purpose the inin which the blade-holder is arranged at an obtuse angle of inclination to the axis of its handle and' in which the spindle of the friction-roller is arranged parallel with the bladeholder and at the same anglev of inclination with the axis of the handle of the blade-holder as the latter. Y p

The invention consists, further, of a razorstropping device comprising atransverse support, two parallel spindlesone for the bladeholder and the other for a friction-rollermeans for supporting the blade-holder and friction-roller at an obtuse angle of inclina- The motion-transmitting gearing was provided with means for checktion to theVv handle of the support, and gearing-for transmitting motion from the spindle of the 'friction-roller to the Aspindle of the blad e-holder and the invention consists, fu rther, of certain additional details of construction, which will be fully described hereinafter and inally pointed out in the claims.

1n the accompanying drawings, Figure l represents a' plan view of our improved razorstropping device shown as applied to a strop. .Fig 2 is a vertical transverse section on line 2 2, Fig. 1, showing the operating-gearing of the stropping device. Fig. 3 is a vertical transverse section on line 3 3, Fig. 1, showing the blade in one position on the strop; and

Fig. 4 is a similar section showing the blade and blade-holder in the opposite position on \the strop.

Similar letters of reference indicate corresponding parts. A r

Referring to the drawings, B represents the handle of our improved stropping device. `The handle B is applied to a transverse support A, which may be made of suitable cast metal or bent up from sheet metal, said transverse support being provided at its center With means for attaching the handle B to the same and with acentral bearing for the spindie g of the blade-holder G. The transverse support A is further provided, at each side of the spindle of the blade-holder G, with socketbearingsy ,d d for the spindles D Dof two friction-rollers F F', which aremade. of leather, rubber, or other suitable material, that produce friction when placed in contact with the strop. The blade-holder G is provided with a longitudinal opening which is adapted'to receive the cutting-blade H. A pinion l f is lkeyed Yto the spindle of the blade-holder and arranged to mesh with toothed segments f f2, 'that are keyed to the spindles D D ofthe ,friction-rollers F F, so that when one of the 1` friction-rollers is turnedby contact with the strop on its axis the blade-holderis moved to one side and when the other roller` is turned it is moved to the opposite side, as shown in Figs. 3 and 4. The edge of the blade is moved in either direction in contact with the strop until it arrives at the end of the stroke, when the blade is reversed by the motion in opposite direction of the handle.

roo

One of the toothed segments of the motiontransmitting gearing is provided with stoppins f3, which project from the saine and which serve to limit the rotative movement of the spindle of the blade-holder by alternately forming contact with the opposite sides of the transverse support A. To the under side of the transverse support A is attached the frame of a holder K, which is provided at its front end with a convex guard-plate K', that is located below the inner end of the blade-holder and which serves for moving the stropping device to and fro along the edge of the strop for producing the stropping action on the blade.

The mechanism so far described and its operation is fully described in the patent heretofore granted to us, and therefore requires no further description.

The improvement consists in arranging the axis of the blade-holder, as Well as the axes of the spindles of the friction-rollers, at an obtuse angle of inclination to the axis of the handle and arranging the supporting-sockets for the spindles of the friction-rollers at a like obtuse angle of inclination to the axis of the handle. This requires that a proper bevel be imparted to the teeth of the motion-transmitting pinionfand to the teeth of the toothed segments f'fz. By this arrangement the friction-rollers instead of being placed parallel with each other and parallel With the spindle of the blade-holder are now arranged converging toward each other and toward the axis of the handle,which is necessary so as to provide a space su dicient for permitting the oscillating tion-rollers, as thereby the edge of the blade when the same is on one or the opposite side of the axis of the handle is parallel with the axis of the adjacent friction-roller. Our improved stropping device is therefore adapted to be operated with a blade-holder arranged at an obtuse angle of inclination to the axis of the handle and renders thereby the stropping device more effective, yas it carries out the principle of stropping more fully described in the pending application hereinbefore referred to.

Having thus described our invention, we claim as new and desire to secure by Letters Patentl. In a raZor-stropping device, the combination, With a transverse support, of a handle for said support, a blade-holder the spindle of which is supported at an obtuse angle of inclination to its handle, a friction-roller the spindle of which is supported at the same angle of inclination to the axis of the handle and gearing for transmitting motion from the spindle of the friction-roller to the spindle ot the blade-holder, substantially as set forth.

2. In a razor-stropping device, the combination, With a transverse support provided with a handle, of a blade-holder the spindle of which is arranged at an obtuse angle of inclination to the axis of said handle, an antifriction-roller at cach side of the handle the spindles of which are arranged at the same angle of inclination to the axis of the handle as the blade-holder, gearing for transmitting motion from the spindle of the antifrictionrollers to the spindle of the blade-holder, and check devices on the gear of one of the roller spindles, substantially as set forth.

In testimony that we claim the foregoing as our invention we have signed our names in presence of two subscribing Witnesses.
